AM654x and AM652x Sitara Arm applications processors are built to meet the complex processing needs of modern industrial embedded products.

The AM654x and AM652x devices combine four or two Arm Cortex-A53 cores with a dual Cortex-R5F MCU subsystem which includes features intended to help customers achieve their functional safety goals for their end products and three Gigabit industrial communications subsystems (PRU_ICSSG) to create a SoC capable of high-performance industrial controls with industrial connectivity and processing for functional safety applications. AM65xx is currently undergoing assessment to be certified by TÜV SÜD

according to IEC 61508.

The four A53 cores are arranged in two dual-core clusters with shared L2 memory to create two processing channels. Extensive ECC is included on on-chip memory, peripherals, and interconnect for reliability. The SoC as a whole includes features intended to help customers design systems that can achieve their functional safety goals (assessment pending with TÜV SÜD). Cryptographic acceleration and secure boot are available on AM654x and AM652x devices in addition to granular firewalls managed by the DMSC.

Programmability is provided by the quad-core Arm Cortex-A53 RISC CPUs with Neon extension, and the dual Cortex-R5F MCU subsystem is available for general purpose use as two cores or it can be used in lockstep to help meet the needs of functional safety applications. The PRU_ICSSG subsystems can be used to provide up to six ports of industrial Ethernet such as Profinet IRT, TSN, or EtherCAT™ (among many others), or they can be used for standard Gigabit Ethernet connectivity.

TI provides a complete set of software and development tools for the Arm cores including Processor SDK Linux-RT, RTOS, and Android as well as C compilers and a debugging interface for visibility into source code execution. Applicable safety documentation will be made available to assist customers in developing their functional safety related systems.

The AM65x GP EVM is a standalone test, development, and evaluation module (EVM) system that lets developers write software and develop hardware for industrial communication-type applications. The GP EVM is equipped with AM6548 processor from TI and a defined set of features to let the user experience industrial communication solutions using serial, Ethernet-based, PCIe, and many other interfaces. Using standard interfaces, the GP EVM can communicate with other processors or systems, and act as a

communication gateway. In addition, the GP EVM can directly operate as a standard remote I/O system or simple sensor connected to an industrial communication network. The embedded emulation logic allows for emulation and debugging using standard development tools such as Code Composer Studio™, from TI, by using the supplied USB cable.

The AM65x GP EVM is a high performance, standalone development platform that enables users to evaluate and develop industrial applications for the Texas Instrument’s K3 System-on-Chip (SoC). The AM65x GP EVM supports the following key features:

• Based on the K3 architecture with Arm

• 4-GB DDR4 supporting data rate up to 1600 MT/s

• 16-GB eMMC Flash

• Full size SD card, up to 64-GB density with UHS-1 support (8-GB UHS-1 card supplied with the kit)

The AM65x Evaluation Module provides a platform to quickly start evaluation of Sitara™ Arm® Cortex®-A53 AM65x Processors (AM6548, AM6546, AM6528, AM6527, AM6526) and accelerate development for HMI, networking, patient monitoring, and other industrial applications. It is a development platform based on the quad core Cortex-A53, dual Cortex-R5F processor that is integrated with ample connectivity such as PCIe, USB 3.0/2.0, Gigabit Ethernet, and more.
